GENERAL
Control systems permit operation of the engine's throttle
and shift mechanisms. They consist of three major com-
ponents; the control, and the throttle and shift cables.
The 378 Vista™ model is equipped with twin lever, single
action shifter and throttle levers. See Figures F1 & F2.
The port shifter lever operates the port engine and the
starboard shifter lever operates the starboard engine.
This is also true for the throttle levers. See Section F2
- Control Operation for further details.

NOTICE
When reversing direction at an engine speed
over 800 RPM, hesitate in neutral long enough
to let the propeller slow its turning to avoid dam-
aging the shifting mechanism.

NOTICE

the shift control. Monitor all instruments while
engine is idling during warm-up.
Additional information on controls and their operation is
discussed in Section F-2 and the engine manufacturer's
information included in the owner's packet.

CONTROL OPERATION
A. General
NOTICE
Do not run a cold motor any faster than neces-
sary to keep motor from stalling. Do not ex-
ceed 2500 RPM in NEUTRAL.
During the general operation of a dual engine boat, it is
advantageous for both engines to be operated at the same
engine speed (rpm). This reduces noise and vibration,
and can increase propulsion system efficiency. Setting
the throttles so the engines are running at the same rpm
(synchronized) can be done by engine sounds or by an
engine synchronizer gauge (as described in Section E-
8K). Attempting to synchronize the engines solely by
using tachometer readings or throttle lever placement gen-
erally will not be effective. When the engines are in proper
synchronization, the throttle levers may not necessarily
be in the same position.
B. Shifting and Control Speed
NOTICE
If your boat is equipped with a non-OEM remote
control system, ask your dealer how to properly
operate it.
1. Move shifter levers to the neutral detent position and
throttle levers to the idle position. Placing the shifter
levers in the neutral detent position will engage neu-
tral start switch and allow engine to start.
